Annoying Check engine light

[SMonaldo]

Your scanner would need to support freeze frame data for any given PID.

I can do that but there is no way to predict the next occurrence.

Once the code sets and it's active, you can connect the scanner and see if there is freeze frame data to go with it. No need to monitor full time. Leave the engine running with the active code and you should be able to see both the code and the freeze frame data, if it's there.

Thanks. The issue that went away for a while after the bank 1 upstream O2 sensor was replaced has now come back, and it went on Friday, Sunday, and again this morning, after going on only twice in 6 weeks prior.

The freeze frame data might be there by viewing a "pending" code.

Freeze frame is on this report attached, does anyone see anything obvious jumping out??
